The invention discloses a wind
turbine generator parameter identification method based on a Bayesian neural network, and the method comprises the following steps: S1, collecting historical data of a wind
turbine generator, and initializing Bayesian neural
network model parameters; S2, dividing historical data of all wind
turbine generators into training data and
test data; S3, calculating networkoutput by using the training data; S4, updating the weight of the Bayesian neural
network model; and S5, calculating a global error, judging whether the requirement is met or not, if so, obtaining a final network weight matrix, and ending the learning
algorithm, otherwise, returning to S3, and entering the next round of learning; and S6, calculating
network output by using the
test data and the network weight to obtain the parameter identification result of the wind turbine generator. According to the method, the Bayesian theory and the neural
network model are combined, compared with a traditional parameter identification method, the method considers the influence of the uncertainty change of the external environment in the identification process, and the method has the advantages that the global error is easy to converge, and the number of iteration steps is small.
